Abstract: Seamed belts having puzzle-cut seam with edges that are themselves puzzle-cut: puzzle-cut on puzzle-cut seamed belts. Such belts beneficially may take the form of imageable seam intermediate transfer belts such as those used in marking machines. Belts are formed from a substrate having a puzzle-cut first end and a puzzle-cut second end that interlock to form a seam. That first end includes puzzle-cut tabs that have puzzle-cut edges and the second end includes puzzle-cut tabs that also have puzzle-cut edges. The first end and the second end interlock such that the puzzle tabs and the puzzle-cut edges mate to form the seam. Beneficially an adhesive is disposed over the seam. If the seamed belt is an imageable seam intermediate transfer belt the substrate is beneficially semiconductive.

The first end includes a first tongue and the second end includes a second tongue that form a rabbeted joint such that the outer surface of the belt is substantially smooth across the seam. An adhesive is disposed over the rabbeted joint. The tongues may include mechanical locking features, such a protrusion and a channel, that mate. The mechanical locking features may be continuous along the seam.

Abstract: A system for manufacturing large quantities of seamed belts for printing systems with controlled imageable seams, which belts require a defined circumference and width, from suitable belt material in a large roll thereof, by feeding a continuous web of that belt material from the roll in (or cut to) a width that is at least as wide as the defined circumference of the finished seamed belt into a seam cutting station, where the opposing side edges of the continuous web of belt material are cut as they move through the seam cutting station into opposing seam-forming mating edge patterns, preferably mating puzzle-cut patterns cut by small movement laser beams on each side of the moving web.

Abstract: Seamed belts, particularly puzzle-cut imageable seam intermediate transfer belts, that have large seam surface areas and puzzle-cut tabs that are resistant to lifting away from the seam. Belts include a substrate having a puzzle-cut first end and a puzzle-cut second end that are interlocked together to form a seam having a kerf. The first end includes a first step and the second end includes a second step. When the ends are interlocked the first step and the second step form a channel. An adhesive is disposed in the channel. The resulting channel beneficially continuously extends along the puzzle-cut seam. When the belt is an imageable seam intermediate transfer belt the substrate takes the form of a semiconductive substrate. Such imageable seam intermediate transfer belts find use in electrophotographic marking machines.

Abstract: Seamed belts, in particular puzzle-cut imageable seam intermediate transfer belts and electrophotographic printing machines that use such transfer belts, that are resistant to unzipping. The seamed belts include a first substrate having a first end and a second end that mate to form a first seam that runs across the first substrate. Along at least one side edge of each end of the first substrate is a cut-out. With the first end and the second end mated to form the first seam the cut-outs align to form a larger cut-out. A second substrate is then fitted into the larger cut-out along a second seam. Beneficially, an adhesive is disposed over the first seam and the second seam. Imageable seam intermediate transfer belts have first and second substrates that are beneficially semiconductive and puzzle-cut seams.

Abstract: Marking machines having imageable seam intermediate transfer belts and toner particles that are “tuned” to that belt. An imageable seam intermediate transfer belt includes a puzzle-cut first end and a puzzle-cut second end that are interlocked along a kerf to form a seam. That kerf has an average width of W. A developer deposits toner particles onto a latent image on a photoreceptor. Those toner particles have an average minimum width (diameter if the particles are spherical) of a size that is similar to W. That is, the kerf width is at least within an order of magnitude of the average minimum width of a toner particle. A transfer station then transfers toner from the photoreceptor to the imageable seam intermediate transfer belt.
